The invention relates to a machine for applying jackets, usually paperjackets, to previously bound books. It has been the usual prior practiceto apply such jackets manually, and this has been troublesome andcostly. The general object of the present invention is to provide amachine which eliminates the manual labor of jacketing the books andwhich applies the jackets entirely automatically. provided a machinewhich is adapted to receive books in vertical positions with the backsupward and which will in sequence preferably open the covers of eachbook, transfer a suitable jacket from a stack and place, it on theopened covers of the book, fold the jacket so that the end portionsthereof will be below and adjacent the covers, and finally close thecovers of the book with the jacket in place.

One of the more specific objects of the invention is to provide asuitable mechanism for feeding books through the machine, preferablyintermittently, and for supporting the books while being so moved, thesaid book moving and supporting mechanism preferably being readilyadjustable for books of different sizes.

Another specific object of the invention is to provide a suitablemechanism operable in timed relationship with other parts for openingthe covers of the books and for supporting the said covers in openpositions.

Another specific object of the invention is to provide a suitablemechanism operable in timed relationship with other parts fortransferring jackets from a stack and for placing them on the opencovers of the books.

Still another specific object of the invention is to provide a suitablemechanism operable in timed relationship with other parts for fol-dingthe jackets to bring the edge portions thereof below and adjacent theinner faces of the open covers of the books.

Still another specific object of the invention is to provide a suitablemeans associated with or forming a part of the folding mechanism forproviding a proper amount of slack in the folded jackets in order topermit the books" to be readily closed with the folded jackets in place.

A still further specific object of the invention is to provide suitablemeans for moving the respective jackets simultaneously and in unisonwith the corresponding books as the books "are moved from the jacketreceiving station, this means assuring proper location of the jackets onthe books when the covers are closed.

A still further specific object of the invention is to provide meansautomatically operable upon failure of the book opening means to open abook for preventing the placement of a jacket by the jacket placingmeans.

A still further specific object of the invention is to In accordancewith the invention there is provide means automatically operable intimed relationship with the folding means for momentarily holding thejackets in folded positions and for then permitting the book covers tomove to closed positions with the folded jackets in place.

Various other specific objects of the invention will be apparent fromthe accompanying drawings and from the following specification andclaims.

In the drawings I have shown in detail a preferred embodiment of theinvention, but it will be understood that various changes may be madefrom the construction shown, and that the drawings are not to beconstrued as defining or limiting the scope of the invention, the claimsforming a part of this specification being relied upon for that purpose.

General organization Referring to the drawings, is the main base onwhich all of the other parts of the machine are supported. Power foroperating the machine is supplied by'means of an electric motor 12supported on a bracket 14 carried by the base 10. Power is transmittedfrom the motor 12 by means of a belt 16 extending over a pulley 18 :onthe motor shaft and over a pulley 2-8 on a transverse drive shaft nearthe middle of the machine. The drive shaft carries a hand wheel 24 bymeans of which the'machine can be operated manually for purposes ofset-up and adjustment. The drive shaft carries a pinion 26 from whichpower is transmitted by gears 28 and 30 to a gear 32 on a maintransverse cam shaft 34. The cam shaft carries various cams whichoperate most of the mechanisms of the machine. One of the said cams isshown at 36 but some of the other cams are not shown in detail. The camsserve to give predetermined properly timed motions to various parts ofthe machine in accordance with well known mechanical principles and donot in and of themselves constitute part of the invention.

For starting and stopping the operation of the machine there is provideda conveniently located hand lever 38 controlling a suitable clutch. Forstarting the operation of the machine, but not for stopping it, there isprovided a foot treadle 40. This treadle is pivoted to the main frame 10at 42 and is connected by means of a link 44 with a lever 46. A spring48 serves to bias the link 44 and the treadle 40 in the upwarddirection. The mechanism for starting and stopping may be ofconventional design and is not shown in detail as it does not constitutea part of the invention.

Mechanism for supporting and moving books The books to which'the jacketsare to be applied are moved horizontally through the machine. The booksto be jacketed may be supplied to the front of the machine manually, 'orby a suitable feeding mechanism which is not shown. The completelyjacketed books may be removed from the rear of the machine manually orby a suitable mechanism which is not shown.

While the invention is not necessarily so limited, the books arepreferably moved intermittently, and are brought to rest in successivestations. The number of stations may be varied, but preferably and asshown, there are four stations designated respectively as I, II, III andIV in Fig. 5. Station I is an idle station designated for'convenience asthe book loading station, station II is the book opening station,station HT is the jacket applying station, and station IV is designatedfor convenience as the book closing station. The drawings show means formoving the books intermittently as is preferred, and this means will bedescribed in detail.

The means for supporting and moving the books is preferably adjustablevertically to provide for books of different widths. This verticaladjustment could be eliminated in a machine intended for use with booksof only one width, but the vertical adjustment is highly desirable andis shown and will be described. The mechanism for supportlng the booksand for moving them through the machine is carried on two slides 50 and52 which are vertically movable in guideways formed in pairs of brackets54, 55 and 56, 57 carried by the base 10 near the ends thereof.Extending longitudinally of the machine and through both slides is ahorizontal shaft 58 squared or otherwise formed at its ends so that itcan be engaged by a wrench 0r crank and readily turned. Associated witheach of the slides 50 and 52 and mounted on the shaft 58 is a bevel gear6% meshing with another bevel gear 62 on a vertical rotatable screw 64.The screw'64 extends at its lower end into a threaded member 65 on thebase. By rotating the shaft 58 the screws 64 can be rotated, thusraising or lowering both of the slides 50 and 52 simultaneously.

Carried by the upper parts of the slides Si) and 52 are longitudinalmembers 66 and 67, shownmore clearly inFig. 6, and the member 67 carriesa supporting device or rail 68 which serves to support and guide thebooks. The rail 68 is preferably replaceable and should have a width thesame as or slightly less than the thickness of the books to be handledby the machine. For thicker or thinner books rails of different widthsmay be substituted. By means of the shaft 58 and the adjusting mechanismthat has been described, the slides 58 and 52 are adjusted vertically soas to bring the rail 68 to such an elevation that the backs of the booksare at a predetermined fixed elevation. The rail is adjusted upward ordownward in accordance with the width of the books.

A suitable means is provided for moving the books longitudinally alongthe rail 68 and through the machine, and this means is preferably anendless chain 70 passing over sprocket wheels 72 and 74 carriedrespectively by the slides 58 and 52. The chain carries a series ofuniformly spaced lugs '76, '76, each of the lugs having a transversepusher '78. The pushers 78 are adapted to extend over the rail 68 and toengage the retrograde ends of the books to move them along the rail. Thelongitudinal members 66 and 67 t are formed to provide a guideway forthe upper run of the chain and for the lugs 76, 76. At the discharge endof the machine there is provided a separate rail section 68 registeringwith the main rail 68 and spaced therefrom to provide a slot 69. Thisslot permits the pushers 78 to move downwardly as the chain passesaround the sprocket wheel 74.

The chain 70 is moved intermittently, the amount of each movement beingequal to the spacing between each two adjacent lugs 76, 76, whichspacing is the same as the spacing between each two adjacent stations,I, II, 111 and IV. For moving the chain there is provided a shaft 80carrying a ratchet wheel 82. Pivotally mounted on the shaft 80 is arocker arm 84 carrying a spring-pressed ratchet 86 adapted to engage theteeth of the ratchet wheel 82. The rocker arm 84 is oscillated by meansof .a link 88 which is connected with a pivoted arm 89 shown in Fig. 5.The arm 89 is oscillated by means of a cam on the shaft 34. The shaft 80carries a bevel gear 90 which meshes with a bevel gear 92 carried by abracket 94. A vertical shaft 96 has splined engagement with the gear 92and this shaft is supported at its upper end by a bearing bracket 98carried by the vertically movable slide 52. The shaft 96 carries a bevelgear 100 meshing with a bevel gear 182 on the shaft which carries thesprocket wheel 74. The ratios of the gears 90 and 92 and of the gears100 and 102 are such that the chain 70 is moved through a distance equalto the spacings between the lugs 76, 76 upon each movement of theratchet wheel 82.

For holding the books upright on the rail 68 at the front portionthereof two horizontal plates 194 and 196 are provided, these beingsupported at a level above that of the said rail. The plates 104 and 106are supported on upward extending portions of the members 66 and 67. Toassist in supporting the books the plates 104 and 106 are provided withangle bars 108 and 110. At the rear end of the machine there are plates112 and 114 similar to the plates 104 and 106 and similarly supported.These plates are provided with angle bars 115 and 116, the rear portionsof which project beyond the plates and are tapered as shown in Fig. 4.The spacing between the plates 112 and 114 is preferably slightly lessthan that between the plates 104 and 106, for the reason that thesaidplates 112 and 114 support the books with the covers open andtherefore engage the book fillers :only and not the complete books.

The plates 104 and 106 and the plates 112 and 114 are preferablyhorizontally adjustable toward and from each other in order toaccommodate books of different thicknesses. The plates are provided witha plurality of sets of transverse guide slots 117 and 118 through whichproject guide members 120 and 122, one set of slots and guide membersbeing shown in Fig. 4 and in 6. For adjusting the plates 104 and 106 andthe plates 112 and 114 there are provided two rockshafts 124 and 126which extend longitudinally of the machine and are supported in suitablebearing brackets carried by the longitudinal members 66 and 67. Therockshafts 124 and 126 respectively carry pluralities of pairs of arms128 and 130, the upper ends of which are entered in notches formed inblocks depending from the outer edge portions of the plates 104 and 106and of the plates 112 and 114. One pair of arms 128 and 130 is shown inFigs. 1 and 6 and another pair 'is shown in Fig. 3. For rocking theshafts 124 and 126 there is provided a transverse shaft 132, shown inFig. 6, mounted in hearings on the slide 52, and having oppositelythreaded portions which engage nonrotatable nuts 134 and 136. Secured tothe rockshafts 124 and 126, preferably as extensions of the arms 128 and130, are arms 138 and 139 which engage the nuts 134 and 136. The shaft132 carries a hand wheel 1-40 by which it may be turned. When the shaft132 is turned by means of the hand wheel 140, the nuts 134 and 136 aremoved in opposite directions thus oppositely rocking the shafts 124 and126 so as to move the plates 104 and 106 and the plates 112 and 114inward or outward simultaneously and to uniform extents.

The books are supported at the front end of the machine, including thebook loading station I, by means of the plates 104 and 106 with theirangle bars 108 and 110. The books are supported at the jacket applyingstation III and at the book closing station IV by means of the plates112 and 114 with their angle bars 115 and 116. When an automatic bookopening means is provided, as is preferred, the last above mentionedplates and angle bars terminate at the book opening station II as shownin Fig. 5, and separate means are provided for supporting the books atthat station, such means being shown in detail in Figs. and 7. The booksupporting elements at station II are transversely movable and areautomatically moved out of their book supporting positions in timedrelation with the book opening mechanism to be presently described. Thispermits the opening of the book by the opening mechanism, and after suchopening the supporting elements are returned to their book supportingposition-s. These supporting elements and parts of the operating meanstherefor are carried by the longitudinal member 67 and are thereforevertically movable with the other book moving and supporting parts, whensuch parts are vertically adjusted in accordance with the width of thebooks to be handled.

At the book opening station there are two oppositely disposed booksupporting plates 142 and 144 which are so positioned and of suchlengths as to be adapted to support the books between the plates 104 and106 and the plates 112 and 114. The plates 142 and 144 are carriedrespectively by arms 146 and 148 which are connected respectively withshort longitudinal shafts 150 and 152 carried by the longitudinal member67. The said shafts are provided respectively with gears 154 and 156which mesh with each other so that the shafts and 152 are turned inopposite directions. The arms 146 and 1-48 have lost motion pivotalconnections with the shafts 150 and 15,2, and as indicated, they arepivotally connected at 158 and 160 with the hubs of the gears 154 and156. .:Springs 1162 and 164 connected With the arms and with the gearstend to relatively move the arms upwardly about their pivotalconnections at 158 and 160.

For operating the shafts 150 and 152 there is provided a rack 166suitably guided for horizontal longitudinal movement. The rack 166carries a roller 168 which is entered in a suitable cam groove in theface of a rotatable cam member 170 carried by the main cam shaft 34. Therack 166 meshes with a gear 172 having a splined connection with avertical shaft 174. The shaft 174 carries near its upper end a gear 176which meshes with a rack 1'78 guided for transverse horizontal movement.The rack 178 has teeth not only at the side thereof which mesh with thegear 176, but also teeth on' the top thereof which mesh with the gear154 on the shaft 150. From the foregoing description it will beunderstood that upon reciprocation of the rack 166 by reason of theengage ment of its roller 168 with the groove in the cam member 170, theshaft 174 is turned, this shaft serving by means of the gear 176 and therack 178 to turn the gears 154 and 156 Thus the arms 146 and 148 aremoved in opposite directions and the plates 142 and 144 are similarlymoved.

By means of the mechanism described the plates 142 and 144 are movedalternately and in properly timed relationship with the other parts ofthe machine between the positions shown in dotted lines in Fig. 7 andthe positions shown in full lines therein. When the plates 142 and 144are in the dotted line positions their inner edges are substantially inalignment with the inner edges of the plates 104 and 106 and the inneredges of the plates 112 and 114, and they thus serve to support thebooks as they move into the book opening station and as they move out ofthe book loading station.

As already described, the plates 104 and 106 and the plates 112 and 114are adjustable transversely to accommodate books of differentthicknesses and provision is made for correspondingly adjusting thedotted line positions of the plates 142 and 144. For this purpose thearms 146 and 148 are provided at the front and rear with longitudinallyextending lugs 180 and 182. It has already been stated that the shafts124, 126 carry several arms 128, 128 and 130, 130 for adjusting theplates 184, 106 and 112, 114. Two of the arms 128 and 130 are positionedadjacent the front edges of the plates 142 and 144 as shown in Fig. 7,and two similar arms, not shown, are positioned adjacent the rear edgesof the said plates. The arms at the front carry rearward projecting pins188 and and the arms at the rear carry similar forward projecting pins.Inasmuch as the pins 188 and 190 are carried by the arms which adjustthe guide plates, it will be seen that they always occupy positionscorresponding to the positions of adjustment of the said plates. As thearms 146 and 148 move toward their dotted line positions, the lugs 180and 182 engage the pins 188 and 190, the upward and inward movement ofthe plates 142 and 144 being thus limited. Such limitation of themovement of the arms and of the plates is permitted by means of the lostmotion connections at 153 and 160 and by the springs 162 and 164. Thusthe operative or dotted line positions of the plates are automaticallyadjusted in accordance with the adjustments of the guide plates 104 and106 and the guide plates 112 and 114.

The timing of the mechanism is such that the plates 142 and 144 are heldin their dotted line positions as each book moves from the book loadingstation I into the book opening station II. As soon as the book reachesthe bQQk opening station, the plates 142 and 144 are
